For an electric vehicle drive motor the properties of high efficiency, high power density and wide speed range are clearly desirable. This paper presents the design of an induction motor for a prototype electric vehicle, namely a Fiat Cinquecento. It is apparent that the design requires a compromise between achieving low losses on one hand and high power density and wide speed range on the other. The vehicle drivetrain consists of a single motor driving the road wheels via a fixed ratio gearbox and differential. The mechanical arrangement of the transmission is simplified by the use of a fixed gear ratio, however this places a demanding specification on the drive motor speed requirements.
